GAT-X105 Strike Gundam (GAT-X105 ストライクガンダム) is one of the five G Weapons developed by the Earth Alliance in collaboration with Mongenroete to combat against ZAFT's powerful mobile suits. Of the five, only the Strike was salvaged during ZAFT's invasion of Heliopolis and would be piloted by Kira Yamato before being modified and handed down to Mu La Flaga.

Unlike the other G Weapons, the Strike does not excel in a specific area but is designed to tackle multiple situations with the use of its Striker pack system, allowing it be outfitted with various packs that provide different weapons and abilities. The Aile Striker is a large jetpack that provides the Strike with speed and maneuverability along with two beam sabers. The Sword Strike adds a shoulder-mounted boomerang and a large anti-ship sword consisting of a solid blade and a beam emitter for a secondary beam blade. The Launcher Striker comes with an extremely powerful beam cannon capable of punching holes through a colony as well as additional side firearms.

Additionally, the Strike can be outfitted with all three Striker packs to become the Perfect Strike, taking advantage of all three Strikers' weapons and equipment, the only change being the addition of three more battery packs to the Aile Striker.
